A Small Business Facing Uncollectible Debt

Scenario

GreenLeaf Landscaping has a customer, Joe’s Cafe, that owes $2,500 for work done three months ago. Joe’s Cafe closed suddenly, leaving no forwarding address.

She also notifies her accountant for tax purposes.

Accounting Decision

Maria decides to use the direct write-off method. She debits Bad Debt Expense for $2,500 and credits Accounts Receivable for the same amount. This removes the uncollectible account from her books and recognizes the loss in the current period. She chooses this method because the amount is small and not material to her financial statements. The direct write-off method is simple but does not follow GAAP for large companies.

Financial Impact

The write-off reduces GreenLeaf’s net income by $2,500. It also lowers accounts receivable on the balance sheet. Maria notes that future credit checks on customers might prevent similar uncollectible debts. The correct spelling uncollectible appears in all her records. She updates her credit policy to need background checks for new clients. This change aims to reduce future bad debt losses.

Net Income: $50,000	Net Income: $47,500
